When Does the Baby Start Moving in the Womb?

Most pregnant people first feel their baby move between 16 and 24 weeks of pregnancy. Those early sensations, called quickening, are subtle enough that many people mistake them for gas or muscle twitches before realizing what they are. The timing varies based on whether this is your first pregnancy, where your placenta sits, and how tuned in you are to the sensation.

What Quickening Feels Like

The first movements don’t feel like kicks. They feel like fluttering, tiny bubbles rising, or gentle taps deep in your lower abdomen. Many people describe it as a sensation similar to gas moving through the intestines, which is why it’s easy to dismiss the first few days of movement without recognizing it.

As weeks pass, the sensations become more distinct and harder to miss. Around 21 to 24 weeks, you may start to feel jerky movements, and you might even see them from the outside. Repeated rhythmic jerks usually mean your baby has the hiccups, which are completely normal and can last anywhere from a minute to an hour. By 25 to 28 weeks, kicks and stretches become more forceful, while the twisting and turning motions you felt earlier shift into squirming and jabbing as your baby grows and has less room to rotate.

First Pregnancy vs. Second or Later

If this is your first pregnancy, you’re more likely to feel movement toward the later end of that 16 to 24 week window. That’s not because first babies move less. It’s because you don’t yet have a frame of reference for what fetal movement feels like, so those early flutters are easier to overlook. People in their second or subsequent pregnancies tend to recognize the sensation earlier, sometimes by 16 or 17 weeks, simply because they know what they’re feeling for.

How Placenta Position Affects Timing

Your placenta’s location plays a real role in when you notice movement. If you have an anterior placenta (meaning it’s attached to the front wall of your uterus, between your baby and your belly), it acts as a cushion that muffles kicks and punches. Most people feel their first kicks around 18 weeks, but with an anterior placenta, you may not feel anything until after 20 weeks. The movements are still happening on schedule. You just can’t feel them as easily through that extra layer of tissue. As your baby gets bigger and stronger in the second half of pregnancy, the difference becomes less noticeable.

Does Body Size Affect What You Feel?

There’s a common assumption that having a higher body weight makes it harder to feel fetal movement. The actual evidence doesn’t support this. A systematic review looking at the relationship between obesity and movement perception found no data showing that people with higher BMI were less likely to perceive their baby’s movements. So if you’re in a larger body and worried you’ll miss early kicks, the research suggests your ability to feel movement isn’t meaningfully different from anyone else’s.

When Your Baby Is Most Active

Once you can feel regular movement, you’ll probably notice your baby has a schedule. Research tracking fetal activity at 20 to 22 weeks found that babies are least active in the morning and most active in the evening. This pattern mirrors what happens near the end of pregnancy, though the differences become more pronounced as your baby grows. Many people notice a burst of activity after meals or when they lie down at night, partly because you’re more still and paying attention, and partly because blood sugar changes can stimulate movement.

At 13 weeks, no consistent daily rhythm exists yet. The pattern of quiet mornings and active evenings emerges around 20 to 22 weeks and strengthens as pregnancy progresses.

Tracking Movement in the Third Trimester

Starting around 28 weeks (or 26 weeks for higher-risk pregnancies like those with twins), it’s helpful to pay regular attention to your baby’s movement patterns. The most widely used approach is straightforward: pick a time when your baby is usually active, start a timer, and count until you feel 10 distinct movements. Kicks, rolls, jabs, and hiccups all count.

There’s no universal time limit for how quickly you should feel those 10 movements, because every baby has a different baseline. What matters most is learning your baby’s normal pattern and noticing when something changes. The general guideline used by most maternity units is that if you focus on movement for two hours and don’t feel at least 10 movements, contact your provider or maternity unit right away.

What Decreased Movement Means

A noticeable decrease in your baby’s usual movement after 28 weeks deserves prompt attention. The Royal College of Obstetricians and Gynaecologists advises that if you’re unsure whether movements have decreased, lie on your left side and focus on what you feel for two hours. If you count fewer than 10 movements in that time, contact your maternity unit immediately rather than waiting until the next day.

Your baby should continue moving right up until labor begins. There’s a persistent myth that babies “slow down” at the end of pregnancy because they run out of room. The type of movement may change (more pushing and stretching, less dramatic somersaults), but the frequency shouldn’t drop off. A real reduction in movement can signal that your baby needs evaluation, and getting checked quickly leads to better outcomes.
